★ 07/13/09 to 07/17/09---start of project
Discuss our team project and set goals
Collect and search journals and information related to our project

★ 07/27/09 to 07/31/09
Laboratory event (summer vacation)

★ 08/03/09 to 08/07/09---preparation for expariment
Prepare for experiment (make LB medium, several antibiotic LB plates and DH5a competent cell)
Transform and do miniprep plasmids contain standard parts.
(BBa_J23100, BBa_J23110, BBa_J23112, BBa_B0034, BBa_B1105, BBa_E0040 and BBa_E1010)

★08/10/09 to 08/14/09 ---preparation for experiment
Transform and miniprep standard parts (RBS, BBa_I15008, BBa_I15009, BBa_S03417, BBa_R0083,
GFP, Terminator, BBa_I714075, crRBS, BBa_K145001, BBa_I719005, RFP, BBa_K113009 and BBa_K124003)
Search DNA sequence of anitigen43 and find that there is 6 PstⅠ restriction sites.

★ 08/17/09 to 08/21/09 ---parts construction
[counter group】
Cut plasmids by restriction enzymes and pick up RBS and taRNA-Term. Ligate these parts and DH5a
was transformed with sample. Do same things with following parts.

This chart suggests that we pick up part 1 and part 2 materials, ligate them, transform DH5a with them,
inoculate that cell and do miniprep after cultivation.

【red light receptor】
Construct parts

【aggregation and lysis】
Order primers which designed to amplify antigen43.
Construct parts.

★ 08/31/09 to 09/04/09 -----parts construction
【counter】
Construct parts.

Make shortage plates and LB medium.
【red light receptor】

【aggregation and lysis】
Check sequence of [a1] and [a2], but cannot read it.
Gel electrophoresis of antigen43 and expression vector pTrc99-NdeⅠ cut by NdeⅠ,
but cannot find appropriate bands.

★ 09/07/09 to 09/11/09
【counter】

【green light receptor】

【aggregation and lysis】
Gel electrophoresis of antigen43 cut by NdeⅠand SpeⅠ.
Gel electrophoresis of expression vector pTrc99-NdeⅠ cut by NdeⅠand XbaⅠ
Do geneclean both of them, ligate them, transform DH5a with ligated sample and inoculate it.
Check sequence of [a1] and [a2] again, but cannot read it.

★ 09/14/09 to 09/18/09
【counter】

Sequence analysis.
【green light receptor】

Sequence analysis
【aggregation and lysis】
Pick up some single colonies from inoculated plate made last week and do direct colony PCR. After PCR,
we check presence of insert DNA in plasmid by electrophoresis but cannot find.
Order primers which break 6 PstⅠsites not to change amino acid sequence.
Try reconstruction of [a1] to [a3].

★ 09/21/09 to 09/25/09
【counter】
From results of sequence analysis, we find we couldn’t construct all of the above counter parts.
And start reconstruction of counter parts ([c1], [c2] [c4] and following parts.)

【green light receptor】

Sequence analysis
【aggregation and lysis】
Gel electrophoresis of antigen43 cut by NdeⅠand SpeⅠ.
Gel electrophoresis of expression vector pTrc99-NdeⅠ cut by NdeⅠand XbaⅠ
Do geneclean both of them, ligate them, transform DH5a with ligated sample and inoculate it.
Try reconstruction of [a4] and [a5].

★ 09/21/09 to 09/25/09
【counter】
Reconstruction of parts ([c3], [c6], [c12] and follwing part)

 Check sequence of reconstruction parts.
【light receptor】
Test red light receptor.

【aggregation and lysis】
Pick up some single colonies from inoculated plate made last week and do direct colony PCR.
After PCR, we check presence of insert DNA in plasmid by electrophoresis but cannot find.
Pick up all colonies and cultivate them and do induction in order to watch out occurrence of aggregation.
But we cannot see aggregation.

★ 09/28/09 to 10/02/09
【counter】
Reconstruction of parts ([c5] and following parts)

Sequence analysis
【light receptor】
Test green light receptor.
【aggregation and lysis】
Try TA cloning (ligation of antigen43 with pGEMT vector).
Transform DH5a with ligated sample, inoculate it, cultivate it and do miniprep.
Try mutation 1st and 2nd PstⅠ sites. After mutagenesis, transform DH5a with ligated sample, inoculate it.
But there is no colony on plate.

★ 10/5/09 to 10/09/09
【counter】

Sequence analysis
【aggregation and lysis】
Check sequence of [a1] and [a2] again, but cannot read full length sequence.
→ Something wrong with Biobrick parts.

★ 10/12/09 to 10/16/09
Start testing all parts.
Prepare for sending parts to MIT
